For instance, it is open in Japanese kokai publication hei 05-20714 communique (patent documentation 1) two optic disc base boards to be implemented bonding technology.Below with reference to Fig. 1 to Fig. 4, this technology is described.
As illustrated in figures 1 and 2, a pair of turntable 101,102 can be disposed relatively, and two optic disc base boards 103,104 that will need to implement adhesion process are implemented fixing by relative these two turntables 101,102 of vacuum suction mode.The turntable 101 that is positioned at downside can be implemented rotating drive by motor 105, and the turntable 102 that is positioned at upside can move by reciprocating mechanism 106 easy on and off.And, can between two optic disc base boards 103,104 at turntable 101,102 places that are fixed on upper and lower sides, supply with bonding agent by rotary coating device 107.Be provided with the configurator 109 with nozzle 108 at rotary coating device 107 places, this configurator 109 is being implemented to support according to the mode that the leading section that makes nozzle 108 can move freely along the radial direction of two optic disc base boards 103,104 that are fixed on turntable 101,102 places.
As shown in Figure 3, rotary coating device 107 can make relative nozzle 108 supply with the bonding agent path 110 of bonding agent and supply with compressed-air actuated pressurized air path 111, merges in the dead ahead of configurator 109.Bonding agent path 110 can be contained in bonding agent supply container 113 in the pressurized tank 112 via receipts, T-valve 114, and filtrator 115, ball valve 116 and needle valve 117 arrive air valves 118 places, and merge with pressurized air path 111 herein.Pressurized air path 111 arrives air valve 118 by compressed-air actuated supply source by solenoid valve 119, and merges with bonding agent path 110 herein.
Adopt this form of the composition, can be by the mode that solenoid valve 119 in T-valve in the bonding agent path 110 114 and the pressurized air path 111 etc. is opened, pressurized air and bonding agent are supplied to configurator 109 in the lump, and then bonding agent is discharged by nozzle 108 places.At this moment, can change the compressed-air actuated pressure that is supplied to configurator 109 places by regulating the mode of air valve 118, and then the bonding dose delivery of being discharged by nozzle 108 is regulated.And the solenoid valve that can adopt electrical control is as above-mentioned air valve 118.
Below with reference to Fig. 4, describe using this manufacturing installation that two optic disc base boards 103,104 are implemented bonding operation.Nozzle 108 is inserted between two optic disc base boards 103,104 that are fixed on turntable 101,102 places, its leading section is positioned near the central portion of optic disc base board 103.In this state, when discharging such as ultraviolet hardening resin 120 bonding agents such as grade by nozzle 108 places, the turntable 101 of rotating drive downside.Like this, just can near the central portion of the optic disc base board 103 of downside, be circle-shaped coating ultraviolet hardening resin 120 (referring to Fig. 4 A).
Subsequently, by reciprocating mechanism 106 turntable 102 that is positioned at upside is descended, the optic disc base board 104 that will be positioned at upside overlaps (referring to Fig. 4 B) with the optic disc base board 103 of downside.By the turntable 101 of the driving force rotating drive downside of motor 105, the turntable 102 of upside is produced follow rotation.At this moment, the ultraviolet hardening resin 120 that is clipped between two optic disc base boards 103,104 will be towards outside perimembranous diffusion (referring to Fig. 4 C).When this range of scatter arrives the assigned position place, the rotation of the platform 101,102 that stops operating.
In this state, standby diffuses to the perimembranous end, the outside (referring to Fig. 4 D) of two optic disc base boards 103,104 to the bonding agent that is made of ultraviolet hardening resin 120.At the state that reaches shown in Fig. 4 D, irradiate ultraviolet beam by ultraviolet radiator 121, ultraviolet hardening resin 120 is implemented cure process.In this way, can produce bonding and adhesion type CD 122 that form to 103,104 enforcements of two optic disc base boards.
Fig. 5 is for representing the planimetric map of adhesion type CD 122 for example.Fig. 6 amplifies and makes the vertical profile outboard profile of thickness deformation for expression to being positioned at wherein all side transparent region enforcement of centre portion.Adhesion type CD 122 comprises the information area 123 that accounts for its most of area, and all side transparent regions 124 that are positioned at central portion.
Should in all side transparent regions 124 be from the center pit 125 of CD 122 central portions zone to 123 formation of information area, wherein include die cavity zone 126.This die cavity zone 126, be by make optic disc base board 103,104 o'clock the die cavity 127 formed zones that must generate.
Below with form for example, the each several part size as the digital video media discs of adhesion type CD 122 representative instances is described.The outside diameter of digital video medium is 120mm, and thickness is 1.2mm, and center pit 125 is 15mm, and it is position about 22mm that die cavity zone 126 is formed on by center to diameter.Bonding agent such as formations such as ultraviolet hardening resins 120 exists with following state.Be that bonding agent is present in the digital video media discs by the mode that extends in the about whole surface of two optic disc base boards 103,104, usually need extend into the position, dead ahead in die cavity zone 126 in general always, and from die cavity zone 126 to the position of 125 of described center pits, often have the air layer 128 that bonding agent fails to arrive.
In this interior all side transparent regions 124 that include air layer 128, often have the situation that makes bad order owing to extension situation by the bonding agent that constitutes such as ultraviolet hardening resin 120 grades.The information that this bad order can not cause being recorded in information area 123 places of digital video media discs occurs bad, only a kind of problem that with the naked eye promptly can find.But this during as merchandise sales, can reduce its commodity value in the digital video media discs.Owing to this reason, the digital video media discs of bad order appears in interior all side transparent regions 124 places, will handle as substandard products usually.
As shown in Figure 5 and Figure 6, bad order stastus format at interior all side transparent regions 124 places is: the bonding agent no show is the not enough A that extends as the die cavity zone 126 of target location, enter to 126 places, die cavity zone always and be the excessive B that extends, bonding agent part occurs and lacks to fall for extension bubble C etc.
Whether the interior all side transparent regions 124 at this CD 122 have bad order, need check after CD 122 completes.Implementing this inspection most common form is the mode of implementing affirmation by people's naked eyes.Yet, no matter be interior all side transparent regions 124 in the CD 122, still extend into the ultraviolet hardening resin 120 at all side transparent regions 124 places in this, all is transparent usually.Therefore, often being difficult to bad order whether occurs by the internal all side transparent regions of naked eyes 124 places judges.Owing to this reason, the photographic means of existing at present utilization such as electric charge coupled mode camera (CCD camera) or the like is implemented to take a picture bad order is implemented the scheme of the optical disk check device of judgement automatically to interior all side transparent regions 124 of CD 122.
Fig. 7 is the outboard profile of an example of this optical disk check device of expression.This optical disk check device is to utilize the center hub 202 that is arranged on CD brace table 201 places, to implementing the location as the CD 122 of checking object.From implement after this localization process CD 122 directly over take a picture as inspection area 204 by interior all side transparent regions 124 of 203 pairs of CDs 122 of electric charge coupled mode camera (CCD camera).At this moment, the interior all side transparent regions 124 in the CD 122, and extend into that the ultraviolet hardening resin 120 at all side transparent regions 124 places all is transparent in this, so distinguish their difficulties.Owing to this reason, also need to use interior all side transparent regions 124 of 205 pairs of CDs 122 of illuminace component to implement illumination.
Yet, because interior all side transparent regions 124 of CD 122 are similar to minute surface, so in the photographic image by electric charge coupled mode camera (CCD camera) 203, the virtual image 205a of illuminace component 205 also can enter in the image.Light 205c will appear in the subrange that lighting device 205 is entered in the inspection area 204 of this CD 122.Therefore, have the uneven problem of visual output signal of electric charge coupled mode camera (CCD camera) 203.
Can implement other optical disk check devices of judging automatically to the bad order of interior all side transparent regions 124 of CD 122, for example in Japanese kokai publication hei 11-328756 communique (patent documentation 2) and TOHKEMY 2000-162147 communique (patent documentation 3), disclose.

After the bonding agent that is made of ultraviolet hardening resin 120 is diffused into the perimembranous end, the outside of two optic disc base boards 103,104 always, utilize ultraviolet radiator 121 to implement the ultraviolet ray irradiation, make ultraviolet hardening resin 120 sclerosis.In this manner, implement to make operation after the extension as ultraviolet hardening resin 120 sclerosis of bonding agent.
By aforesaid each operation, implement two optic disc base boards, 103,104 bonding CDs with formation adhesion type CD 122 are formed operation, thereby make adhesion type CD 122.
As above explanation as device that Fig. 1 to Fig. 3 illustrated for example, be after two optic disc base boards 103,104 are implemented to overlap processing, under situation about two optic disc base boards 103,104 being remained on respectively on the turntable 101,102, the turntable 101 that is positioned at downside is rotated and ultraviolet hardening resin 120 implemented to extend and handle.Relative therewith, the present invention can also adopt other embodiments with form of the composition as described below.Promptly be after coating ultraviolet hardening resin 120 on first optic disc base board 103 that is positioned at downside, another second optic disc base board 104 to be overlapped on first optic disc base board 103.And, second optic disc base board 104 can be taken off from the turntable 102 as holding member, in this state the turntable 101 of downside is implemented rotating drive, and ultraviolet hardening resin 120 is implemented the processing of extending.
At this, this form of implementation can also be in two optic disc base boards 103,104 bonded to each other at least one in, the recording layer that is made of the recording materials such as phase-transition material or the like at its single face is implemented film forming handle, or form the information-bearing face that has such as record groove that is concaveconvex shape or the like at real estate.And, by to the bonding CD that constitutes 122 of this optic disc base board 103,104 enforcements, be positioned at inboard mode to the bonding formation operation of two optic disc base boards, 103,104 enforcements by making record surface or the information-bearing face that processing constitutes to described recording layer enforcement film forming.
And, with respect to this recording layer is implemented optic disc base board 103 or 104 that the information-bearing face was handled or had to film forming, also can make another optic disc base board 104 or the 103 pairs of recording layers implement film forming and handle or make it have the information-bearing face.For this occasion, can constitute double-side type CD 122.Relative therewith, do not implement that the recording layer film forming is handled or not during the configuration information loading end, can form single side CD 122 for another optic disc base board 104 or 103.
For the CD 122 that forms in this manner, can implement interior all side transparent regions 124 with this CD 122 as inspection area 308, and the inspection operation to implementing in the bonding agent extension quality of this inspection area 308 to check.Below with reference to Fig. 8 to Figure 21, this inspection operation is described.
Fig. 8 is used to implement the outboard profile that described inspection operation is used at the optical disk check device of present embodiment for expression.As the optical disk check device of this form of implementation, its basic comprising is with similar with reference to the illustrated device of figure 7, and difference is to use circular lighting device 301 to replace lighting devices 205.
Fig. 9 is the stereographic map of expression circular lighting device 301 usefulness.Figure 10 is near the vertical profile outboard profile the outside perimembranous of expression circular lighting device 301.Circular lighting device 301 constitutes example as one, as Fig. 9 and shown in Figure 10, can be realized by several light emitting diodes (LED) 302 as light source.Promptly be, can lead beam the diffuser plate 303 of diffusion form and be set to tubular shape, and embedded installed several light emitting diodes (LED) 302 at the outside of this diffuser plate 303 end face.And the one side on diffuser plate 303, film forming are formed with first reflectance coating 304 that lid is covering whole surface, the another side on diffuser plate 303, and film forming is formed with only to cover covers near second reflectance coating 305 of outside perimembranous.
For instance, circular lighting device 301 can also be made of the fluorescent light that the diffuser plate of looped-shaped bending lid cover.Promptly be, as long as have can be with the light beam that is gone out by light source irradiation for circular lighting device 301, the function that diffuses into uniform beam by diffuser plate gets final product, to the not restriction of its kind.
In the present embodiment, circular lighting device 301 as shown in Figure 8 is fixed on electric charge coupled mode gamma camera (CCD gamma camera) 203 places by lighting device holding member 306., also according to not implementing direct reflection way the surface has been implemented to handle such as the low reflection of " frosted blackening " or the like at CD brace table 201 to the illumination beam that comes by upside.And positioning supports is at the central shaft of the CD 122 at CD brace table 201 places, the central shaft of electric charge coupled mode gamma camera (CCD gamma camera) 203 and the central shaft of circular lighting device 301, and it all overlaps on same axle.
Adopt this form of the composition, when CD 122 is implemented to check, can implement: will be as the CD 122 of checking object, opsition dependent not flowing mode is supported on operation on the CD brace table 201; Optical axis and the central shaft that is supported on the CD 122 on this CD brace table 201 circular lighting device 301 disposing that coincide is implemented illumination, and utilize the illumination beam that provides by diffuser plate 303 in the form of a ring the inspection area on the CD 122 308 to be implemented the operation of illumination by upside; And utilize optical axis and the central shaft that is supported on the CD 122 on this CD brace table 201 coincide configuration, as the electric charge coupled mode gamma camera (CCD gamma camera) 203 of imaging device, by upside the inspection area on the CD 122 308 is implemented the operation that videotapes.
At this moment, though with same as the lighting device 205 that Fig. 7 illustrated for example, also will entering by electric charge coupled mode gamma camera (CCD gamma camera) 203 with not changing, circular lighting device 301 videotapes in the image of acquisition.Yet in the present embodiment, the video scope 307 of circular lighting device 301 will be covered fully and cover inspection area 308.Therefore, videotaping in the video of acquisition, local light and shade difference can not occur, thereby can obtain uniform image by electric charge coupled mode gamma camera (CCD gamma camera) 203.Adopt this mode, can detect in the inspection area 308 of CD 122 whether have bonding agent reliably.
At this, for can be according to the mode of the complete inspection in the CD 122 zone 308 being implemented cover fully, the light of circular lighting device 301 is injected, also need be concerned, electric charge coupled mode gamma camera (CCD gamma camera) 203 and circular lighting device 301 etc. are implemented to set according to certain location.Below this certain location relation is described.
If getting the inside diameter of inspection area 308 is S1, the outside diameter of checked inspection area 308 is S2, the inside diameter of the circular lighting device of injecting 301 is D1, the outside diameter of injecting the circular lighting device 301 of light is D2, the illuminating part inside diameter of circular lighting device 301 is L1, the illuminating part outside diameter of circular lighting device 301 is L2, the distance that the lower end of circular lighting device 301 and CD are 122 is LD, the distance that first principal point position H1 on the electric charge coupled mode gamma camera (CCD gamma camera) 203 and CD are 122 is HD, and then actual circular lighting device 301 has similarity relation with the virtual image 301a that this circular lighting device 301 generates in CD 122 images.Thus:
HD∶D1＝(HD+LD)∶L1
HD∶D2＝(HD+LD)∶L2
Set up.Above-mentioned equation can be expressed as:
L1＝D1(1+LD/HD)
L2＝D2(1+LD/HD)。
At this moment,
D1＜S1 and D2＞S2,
So can be according to the mode of inspection area 308 being implemented cover fully, circular lighting device 301 injected by electric charge coupled mode gamma camera (CCD gamma camera) 203 videotape in the image of acquisition.Therefore, when
L1＜S1(1+LD/HD)
L2＞S2(1+LD/HD)
The time, for implementing the condition of good detection to whether having bonding agent.
When L1 was too small, the image that is positioned at the outer circumferential side place in can not the inspection area 308 to CD 122 videotaped.Therefore, L1 need be set greater than a certain value.The size of L1 can be found the solution by next equation.
(HD-LD)∶L1＝HD∶S2，
Can have thus:
L1＞S2(1-LD/HD)，
Therefore:
S2(1-LD/HD)＜L1＜S1(1+LD/HD)。
Can be in this manner, design inspection body 351 as shown in Figure 8.Adopt the inspection body 351 of design like this, not only the light of circular lighting device 301 can be injected, and the operating distance of 203 of CD 122 and electric charge coupled mode gamma cameras (CCD gamma camera) can be fully guaranteed according to the mode that covers complete inspection zone 308 in the CD 122 fully.
To the inspection area 308 that the extension quality of bonding agent is implemented inspection, its inside diameter S1 is generally about 15mm, and outside diameter S2 is generally about 40mm.
Figure 11 is the block scheme that is electrically connected of this optical disk check device of expression.As shown in the figure, in this testing fixture, be provided with microcomputer 404, it is by the read-only memory (ROM) 402 of fixed data of implementing various calculation process and controlling the central processing unit (CPU) 401, storage control program etc. of each parts, and constitutes with the random access memory (RAM) 403 that can free rewrite method stores variable data.Each parts is connected with this microcomputer 404 by system bus 405.Each parts that is connected microcomputer 404 places can be video memory 406, electric charge coupled mode gamma camera (CCD gamma camera) 203, circular lighting device 301, display 407 and bonding with rotary coating device 107 in the mechanical hand 408 or the like at CD.As shown in the figure, electric charge coupled mode gamma camera (CCD gamma camera) 203 is by interface unit 409, and circular lighting device 301 is by controller 410, and display 407 is by controller 411, rotary coating device 107 links to each other with microcomputer 404 respectively by controller 412.
Electric charge coupled mode gamma camera (CCD gamma camera) 203 delivered in the microcomputer 404 by the visual output signal that interface unit 409 will videotape acquisition.
Microcomputer 404 will be kept at video memory 406 by the visual output signal that electric charge coupled mode gamma camera (CCD gamma camera) 203 is sent here, and shows signal will be sent to the controller 411 of display 407.In this way, this controller 411 can the corresponding shows signal of being sent here by microcomputer 404, drive controlling display 407, and the image that electric charge coupled mode gamma camera (CCD gamma camera) 203 is videotaped acquisition shows at display 407.
At this moment, microcomputer 404 can also be implemented to distinguish to the visual output signal that is sent by electric charge coupled mode gamma camera (CCD gamma camera) 203 according to certain threshold value, makes its in vain black binaryzation (binary conversion treatment device).Therefore, display 407 videotapes the former image of acquisition except showing electric charge coupled mode gamma camera (CCD gamma camera) 203, can also show the image after the white black binary conversion treatment.
And microcomputer 404 can also be according to such as the control program that is stored in read-only memory (ROM) 402 places, freely controls the aperture, shutter speed, light sensitivity of electric charge coupled mode gamma camera (CCD gamma camera) 203 etc.
The control signal that can also provide according to microcomputer 404 by controller 410 is implemented drive controlling, is implemented to regulate to the briliancy of circular lighting device 301.
The control signal that rotary coating device 107 can provide according to microcomputer 404 by controller 412 is implemented drive controlling, is implemented control to air valve 118.Like this, just, can freely change the discharge rate of bonding agent (ultraviolet hardening resin 120).Perhaps, also the control of implementing by the discharge rate of 107 pairs of bonding agents of rotary coating device (ultraviolet hardening resin 120) can be replaced with the control that the velocity of rotation of two optic disc base boards 103,104 is implemented.
The control signal that can also provide according to microcomputer 404 by the drive controlling that controller 412 is implemented, is implemented drive controlling to the not shown motor of rotary coating device 107.And described motor, be located at the position of nozzle 108 is implemented to regulate in travel mechanism's device of usefulness (referring to Fig. 1 and Fig. 2).Can freely change the drain position of 103,104 pairs of bonding agents of relative two optic disc base boards (ultraviolet hardening resin 120) by above-mentioned drive controlling rotary coating device 107.
The functional-block diagram that Figure 12 uses as the optical disk check device of the invention described above embodiment for expression.Various functions in this functional-block diagram, can be according to the control program that is stored in such as read-only memory (ROM) 402 places, with reference to being kept at the various parameters that random access memory (RAM) 403 (such as being reserve battery storer and non-volatile storage or the like) is located, finish by the control of the various calculation process of implementing based on microcomputer 404.
At first, the visual output signal that image parsing control part 501 reading electric charges coupled mode gamma cameras (CCD gamma camera) 203 provide also is stored in video memory 406 places, utilize a certain threshold value be stored in inspection condition reservoir 502 places that this image output signal is implemented white black binary conversion treatment simultaneously, and with the data storing after the binary conversion treatment at binaryzation data storing unit 503 places.At this moment, according to making the zone that does not have bonding agent (ultraviolet hardening resin 120), exist the zone of bonding agent (ultraviolet hardening resin 120) to represent as the black pictorial data as the white print image data.Whether good detection unit 504 is with reference to the binaryzation data that are stored in binaryzation data storing unit 503 places, whether good (the good decision maker whether in 308 places, inspection area of judging CD 122, well whether judge operation, whether bonding agent extension quality is well implemented to judge the operation of usefulness according to the visual output signal that provides by electric charge coupled mode gamma camera (CCD gamma camera) 203) as imaging device.At this moment, whether good detection unit 504 can judge whether the inspection area 308 of CD 122 is good according to being stored in the inspection data of checking with data storing unit 505 places.And whether good detection unit 504 can also the check result that bonding agent is too much or not enough be stored in the check result reservoir 506.
At this, circular lighting device 301 can also adopt fluorescent light as previously mentioned.Yet, when adopting fluorescent light to constitute circular lighting device 301, all can produce briliancy in the electrode part in any case and descend, the problem that luminance nonuniformity is even.Therefore, in order addressing this problem, can also to resolve in the control part 501 at this moment, the visual output signal that is provided by electric charge coupled mode gamma camera (CCD gamma camera) 203 to be implemented the shade correction, to eliminate the even problem of luminance nonuniformity such as image.
Binaryzation data storing unit 503 by such as several or tens form, store the repeatedly binaryzation data that obtain when CD 122 is checked.Check condition enactment changing unit 507 with reference to these data, (pass decision maker, pass and judge operation) judged in the passing of checking state.For instance, be the data of the bad product of expression, and its trend is when going out same tendency in repeatedly binaryzation data, may be since working condition change or material change in batches produce.At this moment, the inspection condition that is stored in inspection condition reservoir 502 places does not have suitable correction.And for instance, can also implement equalization to the repeatedly binaryzation data that are stored in binaryzation data storing unit 503 places handles, when surpassing a certain threshold value of relative predicted mean vote setting, can rewrite the inspection condition that be stored in inspection condition reservoir 502 places by checking condition enactment changing unit 507 for this mean value.
At the condition of inspection reservoir 502 places, store the foregoing visual output signal that electric charge coupled mode gamma camera (CCD gamma camera) 203 is provided and implementing the threshold value that white black binary conversion treatment is used, in addition, can also store the data such as shutter speed, aperture, light sensitivity of illumination, the electric charge coupled mode gamma camera (CCD gamma camera) 203 of circular lighting device 301.(implement the threshold value that white black binary conversion treatment is used in the inspection condition that is stored in aforesaid inspection condition reservoir 502 places by 507 pairs of inspection condition enactment changing units as the visual output signal that electric charge coupled mode gamma camera (CCD gamma camera) 203 is provided, the shutter speed of the illumination of circular lighting device 301, electric charge coupled mode gamma camera (CCD gamma camera) 203, aperture, light sensitivity etc.) when implementing change, image is resolved control part 501 can implement checked operation according to inspection condition after changing by check beginning next time.
Check result reservoir 506 by such as several or tens form, store the repeatedly check result that obtains when CD 122 is checked.At this moment, storage is the too much or not enough check result of relevant bonding agent (ultraviolet hardening resin 120).Do not occur when too much or not enough at bonding agent (ultraviolet hardening resin 120), its check result can not be stored in the check result reservoir 506.
For instance, rotary coating uses data setting changing unit 508 with reference to this check result, when surpassing certain threshold value that relative predicted mean vote sets for the mean value of check result repeatedly, rewriting is stored in the rotary coating data (setting value change device, setting value change operation) of rotary coating with data storing unit 509 places.Promptly be, storing the parameter relevant with the bonding agent drain position in rotary coating with data storing unit 509 with the bonding agent discharge rate of rotary coating device 107, when driven in rotation apparatus for coating 107, rotary coating control part 510 can be implemented drive controlling to rotary coating device 107 according to these parameters.Therefore, when the rotary coating that is stored in aforesaid rotary coating usefulness data storing unit 509 places is implemented change with data, can change the bonding agent discharge rate and the bonding agent drain position of rotary coating device 107.
Be exactly specifically, when the inspection area of CD 122 308 place's bonding agents (ultraviolet hardening resin 120) are not enough, can be according to the bonding agent discharge rate that can increase rotary coating device 107 to the mode that this enforcement in shortage replenishes, or the bonding agent drain position of mobile rotary coating device 107.On the contrary, when the inspection area of CD 122 308 place's bonding agents (ultraviolet hardening resin 120) are too much, can cross the bonding agent discharge rate that multi-mode mode reduces rotary coating device 107 according to eliminating this, or the bonding agent drain position of mobile rotary coating device 107.
At this moment, can regulate the bonding agent discharge rate of rotary coating device 107 as follows.Promptly according to the control signal that provides by microcomputer 404, the drive controlling of utilizing controller 412 to implement is implemented control to air valve 118, and then the discharge rate of change bonding agent (ultraviolet hardening resin 120), or the velocity of rotation of control optic disc base board 103,104.
Figure 13 checks for expression is stored in the figure of the inspection in the data storing unit 505 with an example of data.As shown in Figure 13, check that with data be respectively by seeing through regional minimum area 551, setting through the value of regional maximum area 552, marginal portion number 553, agglomerate part number 554.In the inspection area 308 of CD 122, bonding agent (ultraviolet hardening resin 120) too much by will relatively implementing to judge as the white print image data of value that sees through regional minimum area 551 settings and collection.Promptly be, if the area of being represented by the white print image data likens to into the area value of the setting that sees through regional minimum area 551 is little, just can judge that bonding agent (ultraviolet hardening resin 120) is too much.
Relative therewith, bonding agent (ultraviolet hardening resin 120) will be not enough by implementing to judge as the mode that the area that sees through regional maximum area 552 value of setting and the white print image data of representing to gather compares.Promptly be, if the setting value that the area of expression white print image data likens to seeing through regional maximum area 552 is big, just can judge bonding agent (ultraviolet hardening resin 120) deficiency.
At this, being stored in as shown in figure 13 checks with the inspection in the data storing unit 505 only be an example with data, other forms of inspection can also checked with in the data storing unit 505 with data storing.
Figure 14 checks for expression is stored in the figure of the inspection in the data storing unit 505 with another example of data.When Figure 14 illustration, check with data respectively by non-ly seeing through regional minimum area 561, non-ly seeing through the value of regional maximum area 562, marginal portion number 553, agglomerate part number 554 and set.In the inspection area 308 of CD 122, bonding agent (ultraviolet hardening resin 120) is not enough to be implemented to judge by the mode that will compare as the area value that the non-black pictorial data that sees through the area value of regional minimum area 561 settings and represent to gather is represented.Promptly be, if the area value of being represented by the black pictorial data likens to into non-setting value through regional minimum area 561 is little, just can judge bonding agent (ultraviolet hardening resin 120) deficiency.
Relative therewith, bonding agent (ultraviolet hardening resin 120) is too much by will be as the non-setting value that sees through regional maximum area 562, and the mode that the area value of representing with the black pictorial data of gathering compares is implemented judgement.Promptly be, if the area value of being represented by the black pictorial data likens to non-setting value through regional maximum area 562 is big, just can judge that bonding agent (ultraviolet hardening resin 120) is too much.
Figure 15 checks for expression is stored in the again figure of an example of the inspection in the data storing unit with data.
When Figure 15 illustration, check with data respectively by seeing through regional minimum area 551, setting through the value of regional maximum area 552, marginal portion number 553, agglomerate part number 554.And, see through regional maximum area 552 and be divided into a-quadrant 571 and B zone 572, thereby can implement to judge to each zone respectively.This moment CD 122 inspection area 308 in the too much or not enough decision procedure of bonding agent (ultraviolet hardening resin 120), with as identical during the illustrative inspection of Figure 13 usefulness data.
Figure 16 checks for expression is stored in the figure of the inspection in the data storing unit with the another example of data.When Figure 16 illustration, check with data and set through regional minimum area 561, the non-value that sees through regional maximum area 562, marginal portion number 553, agglomerate part number 554 by non-respectively.And, non-ly see through regional minimum area 561 and be divided into a-quadrant 571 and B zone 572, thereby can implement to judge to each zone respectively.At this moment, the too much or not enough decision procedure of bonding agent in the inspection area 308 of CD 122 (ultraviolet hardening resin 120) is identical when using data with the inspection shown in Figure 13 example.
Below, the number of edges among Figure 13, Figure 14, Figure 15, Figure 16 553, agglomerate number 554, a-quadrant 571, B zone 572 are described.
At first, marginal portion number 553 is described referring to figs. 17A through Figure 17 C.Figure 17 A to Figure 17 C the synoptic diagram that the state of bonding agent (ultraviolet hardening resin 120) when too much or not enough used occurs for interior all side transparent regions 124 places that are illustrated in CD 122 for example.Rectangular area is represented the synoptic diagram of the too much or not enough state that bonding agent (ultraviolet hardening resin 120) is different respectively among the enlarged drawing 17A shown in Figure 17 B or Figure 17 C.
State shown in Figure 17 B is the local state that appears in the die cavity zone 126 of bonding agent (ultraviolet hardening resin 120).At this moment, owing to be unfavorable in appearance, so it is bad to be judged to be the bonding agent extended state.Relative therewith, at the state shown in Figure 17 C, bonding agent (ultraviolet hardening resin 120) evenly only has any to overflow in die cavity zone 126.At this moment, compare with Figure 17 B, no matter it is bonding agent (ultraviolet hardening resin 120) overflows the area size, harmless to outward appearance.Therefore at this moment, should judge that the extended state of bonding agent is good.
Hence one can see that, and contrast can think that with reference to figure 17B and Figure 17 C iff considering the area size simply, not necessarily the extension state to bonding agent gives suitable judgement.Promptly be also must whether well implement to judge to the bonding agent shape of overflowing.In this form of implementation, also with the imaginary circular path among Figure 17 A to Figure 17 C, be stored in and check in the data storing unit 505, so can also have marginal portion jumpy to implement to detect producing in the visual output signal on this circular path (signal after the black in vain binary conversion treatment).If the number of this marginal portion is than checking that the value of setting with the marginal portion number in the data storing unit 505 553 (threshold value) is big, can judge at interior all side transparent regions 124 places of the inspection area 308 of CD 122, the shape defect of bonding agent (ultraviolet hardening resin 120).
Suitable when this determination processing mode and presentation graphs 17B and Figure 17 C.In the diagram part of the state shown in Figure 17 B, have four marginal portions (marginal portion by * expression).Relative therewith, under Figure 17 C state, there is not this marginal portion.Therefore, can with the condition judgement shown in Figure 17 B bonding agent extended state " bad ", be " well " with the condition judgement shown in Figure 17 C.
Below with reference to Figure 18, Figure 13 is described to " agglomerate part number " 554 shown in Figure 16.The synoptic diagram that Figure 18 uses when bonding agent shape defect (bubble) state occurring for interior all side transparent regions 124 places that are illustrated in CD 122 for example.Under state as shown in figure 18, in the bonding agent (ultraviolet hardening resin 120) bubble 601 appears.Bubble 601 is answered in the extension region bonding agent (ultraviolet hardening resin 120), can think that the part lacks the part of bonding agent (ultraviolet hardening resin 120).When having several this bubbles 601, owing to be the unfavorable shape defect of outward appearance, so it is bad to be judged to be the bonding agent extended state.
And in the present embodiment, white print image data in the visual output signal after can the reference white black binary conversion treatment, use " label for labelling method " in the image processing method, to be island independently white portion implement to detect and affix label successively from top to bottom.Adopting the white portion after this label for labelling method is handled is bubble 601.In example shown in Figure 180, have three independently bubbles 601 at certain regional area.Implement numeration to adopting the number of regions after this label for labelling method is handled, if the value that this numeric ratio inspection is set with the agglomerate part number in the data storing unit 505 554 is big, can judge in interior all side transparent regions 124 of the inspection area 308 of CD 122 shape defect of bonding agent (ultraviolet hardening resin 120).
Below with reference to Figure 19, to describing as Figure 15, " a-quadrant " 571 and " B zone " 572 shown in Figure 16.The synoptic diagram that state when Figure 19 bonding agent (ultraviolet hardening resin 120) shape defect occurs for interior all side transparent regions 124 places that are illustrated in CD 122 is for example used.As shown in figure 19, bonding agent (ultraviolet hardening resin 120) shape defect at interior all side transparent regions 124 places of CD 122 refers to bonding agent (ultraviolet hardening resin 120) and extends not enough along the radial direction of CD 122 sometimes.At this moment, owing to be unfavorable in appearance, so it is bad to be judged to be the bonding agent extended state.Yet at this moment, the area of the extension deficiency of bonding agent (ultraviolet hardening resin 120) may and be not more than a certain degree, so only by simple area relatively, cannot be judged this phenomenon of extending deficiency sometimes.
In this form of implementation, the decision threshold that becomes the B zone 572 of outer circumferential side is according to setting than the stricter mode of decision threshold that becomes the a-quadrant 571 of all sides in the CD 122.Below this stricter setting means is specified.Illustrative by Figure 15, be stored in the inspection checked with data storing unit 505 places with in the data, as the value that sees through regional maximum area 552, that sets in B zone 572 is smaller.Equally illustrative by Figure 16, be stored in the inspection checked with data storing unit 505 places with in the data, as the non-value that sees through regional minimum area 561, that sets in B zone 572 is smaller.Adopt this mode, can judge that the bonding agent (ultraviolet hardening resin 120) of the outer circumferential side that is positioned at CD 122 extends not enough according to than the stricter decision procedure of interior all sides.For instance, adopt this form of the composition, can be illustrated, the extension of the bonding agent (ultraviolet hardening resin 120) that extends along the radial direction of CD 122 is not enough implements suitable judgement to Figure 19.
The process flow diagram that Figure 20 uses as the treatment scheme in the optical disk check device of the invention described above form of implementation for expression.Microcomputer 404 obtains visual output signal (step S101) by electric charge coupled mode gamma camera (CCD gamma camera) 203 places, according to the threshold value that is set in inspection condition reservoir 502 places visual output signal is implemented white black binary conversion treatment (step S102, the binary conversion treatment device, the binary conversion treatment operation).And, the data after this white black binary conversion treatment are sent to binaryzation data storing unit 503 places (step S103).
Transmit and be stored in white black binaryzation data in the binaryzation data storing unit 503 according to data, successively to the bonding agent (ultraviolet hardening resin 120) at interior all side transparent regions 124 places of CD 122 whether extend not enough implement to judge (step S104), extend and whether excessively implement to judge (step S105), whether the marginal portion number too much implements to judge (step S106), and whether agglomerate part number too much implements to judge (step S107).(result of determination among the step S104 is Y for detecting by these result of determination when bad, result of determination among the step S105 is Y, result of determination among the step S106 is Y, result of determination among the step S107 is Y, good decision maker whether, well whether judge operation, whether bonding agent extension quality is well implemented to judge the operation of usefulness according to the visual output signal that provides by electric charge coupled mode gamma camera (CCD gamma camera) 203 as imaging device), wrong (step S109) found in report.This report of finding wrong usefulness can be finished by demonstrate the discovery error message such as display 407.
At this, by well whether judging result of determination that operation (operation of whether bonding agent extension quality well being implemented to judge according to the visual output signal that is provided by the electric charge coupled mode gamma camera (CCD gamma camera) 203 as imaging device) obtains, can also implement the bad CD 122 of this appearance is implemented the selection operation of selecting for bonding agent extension quality occurring when bad.Implementing other forms of the composition of this selection operation, can be the bad CD 122 of this appearance to be implemented the selection form removed with not shown robot apparatus etc. from the CD brace table 201.More specifically, can also be CD 122 to be taken off from CD brace table 201 with robot apparatus etc., the corresponding whether good result of determination of judging operation is implemented differentiation and is sent to the selection form of different predetermined location good product and bad product.Processing is moved in this transmission that utilizes robot apparatus or the like from CD brace table 201 CD 122 to be implemented, and can adopt prior art to realize easily.
And, when (result of determination among the step S104 is Y) and extension are excessive when being the extension deficiency for result of determination (result of determination among the step S105 is Y), will represent that also the data of this testing result are sent to check result reservoir 506 places (step S108).

S2(1-LD/H)＜L1＜S1(1+LD/HD)
L2＞S2(1+LD/HD)。
By calculating, have:
6.8＜L1＜27.4
L2＞73.2。
Yet using electric charge coupled mode gamma camera (the CCD gamma camera) 203 of C type support lens specification and the mounting screw length between lens 203a is 1 inch (25.4mm), and the external diameter of lens 203a is generally than about its big 30mm.Therefore can not have:
L1＜27.4
Therefore, this setting makes the above embodiment of the present invention not implement.
Figure 22 is that explanation is when the optical disk check device (inspection body 351) that uses as shown in figure 21, make the video reduced at the internal side diameter place of the inspection area 308 that is positioned at CD 122, and then the outboard profile that the operation that this video is removed from the internal side diameter of the inspection area 308 of CD 122 is used.

Close this position:
S2(1-LD/HD)＜L1＜S1(1+LD/HD)
L2＞S2(1+LD/HD)，
By calculating, have:
9.0＜L1＜26.6
L2＞71.0。
And, can make the illuminating part inside diameter L1=20mm of circular lighting device 301, illuminating part outside diameter L2=80mm projects the about 11.3mm of lighting device inside diameter D1=at CD 122 places, projects the about 45mm of lighting device outside diameter D2=at CD 122 places.Adopt this mode, can make inside diameter, the outside diameter of the illuminating bundle that projects CD 122 places, all enlarge, so can not have the part that circular lighting device 301 can not be implemented the light beam projection than inspection area 308 (inside diameter S1:15mm, outside diameter S2:40mm).Therefore, can in the whole zone of inspection area 308, the extension quality of bonding agent be implemented to check reliably.
